<span> Ok, so slope of the lane gives the ball a constant acceleration of 1.8 m/s for 2.5 s
[lane slope = arcsine (1.8/9.8) = 10.6°]
which increases speed of the ball by
1.8(2.5) = 4.5 m/s
The ball reaches the pins with a speed = 7.6 m/s, so it must have left Josh's hand with a speed of
7.6 - 4.5 = 3.1 m/s ANS</span>
It most likely wont explode right away but the fumes from the heated pickle might put you on a mild high if you breathe it in a lot...
I believe the density will decrease, because if you look at the equation d=m/v. This can also be written as d=m(1/v). So if you increase volume, let's say you increase from 10ml to 1000ml. And keeping mass same, say 5 grams,then instead of having 1/10= 0.1ml then putting the equation together as 5x0.1. You will have for the second equation 5x(1/1000ml)= 5x0.001. You can see for yourself after multiplying these 2 values from the different equation which density value is smaller and larger.
Answer:
Option D (none are correct) is the appropriate solution.
Explanation:
- After yet another workout, a cool or calming down allows the breathing as well as pulse rate to recover more quickly.
- It will also assist to eliminate the lactic acid build-up during the exercise, eventually increasing the muscle soreness with delayed onset. Wind yourself off for 5 to 10 minutes by taking public transportation a stationary bicycle.
Some other three scenarios do not correspond to something like the situation described. So, this same correct decision is the one above.
I believe “C” is the answer
